Funeral services will be held tomorrow (Tuesday), for a Harlan woman who died in a crash Friday afternoon on Interstate 80, in Pottawattamie County. The Iowa State Patrol says 22-year old Nicollette “Nikki” Johnston died when her car crossed the median near Avoca, and was struck broadside by a semi.

The accident happened about two-miles west of the Avoca exit, at around 1-p.m., Friday. Officials says Johnston’s 2006 Saturn was traveling west on I-80, when, for reasons unknown, the car went out of control, entered the median, spun counterclockwise and came to rest on the eastbound lanes of I-80, where it was struck broadside by a semi. The truck impacted the car on the driver’s side, causing it to enter the median, where it came to rest.

The semi, driven 45-year old Bret Roberts, of Estherville, crossed the median and came to rest on the westbound lanes of I-80. The accident, which remains under investigation, closed the interstate in both directions, for nearly 4 hours. A Mass of Christian Burial service for Nikki Johnston will be held 11-a.m. Tuesday, at St. Michael’s Catholic Church, in Harlan.
